Spôsob a zariadenie na optimalizáciu riadenia procesu a monitorovania procesu v sústave na výrobu cestovínA method and apparatus for optimizing process control and process monitoring in a pasta manufacturing system
Oblasť technikyTechnical field
Vynález sa týka spôsobu optimalizácie riadenia procesu a monitorovania procesu v sústave na výrobu cestovín, najmä krátkych a dlhých cestovín, ako aj zariadenia na uskutočňovanie tohto spôsobu.The invention relates to a process for optimizing process control and process monitoring in a pasta production system, in particular short and long pasta, as well as apparatus for carrying out the method.
Doterajší stav technikyBACKGROUND OF THE INVENTION
Priemyselná výroba cestovín sa už realizuje s pomerne vysokým stupňom automatizácie. Týka sa to napríklad čiastkových procesov lisovania surových cestovín a sušenia a ochladzovania cestovín. Tak napríklad dokument EP-A-0 129 892 B1 opisuje sústavu a spôsob sušenia dlhých cestovín v plynulej prevádzke s riadeným ohrievaním, zvlhčovaním, sušením a ochladzovaním cestovín. Zadávajú sa teplotné časové režimy v turbosystéme. Dokument EP-A-0 540 699 B1 opisuje pokročilejší spôsob regulácie vlhkosti produktu, aby sa zabránilo lámaniu cestovín po ich vysušení a pri balení. Reguluje sa teplota a vlhkosť vzduchu. V poslednej fáze sušenia pritom prebieha v ešte teplom stave cestovín povrchové pridávanie vody a teplota cestovín sa bezprostredne po pridaní vody znižuje na hodnotu pod 60 °C. Podobné riešenie využitím hodnoty AW opisuje dokument EP-A-0 322 053 B1.The industrial production of pasta is already realized with a relatively high degree of automation. This concerns, for example, the partial processes of pressing raw pasta and drying and cooling the pasta. For example, EP-A-0 129 892 B1 describes a system and method for drying long pasta in a continuous operation with controlled heating, humidification, drying and cooling of pasta. Temperature time modes in the turbosystem are entered. EP-A-0 540 699 B1 discloses a more advanced method of controlling product moisture to prevent the pasta from breaking after drying and packaging. Temperature and humidity are regulated. In the last drying phase, the surface addition of water takes place in the still warm state of the pasta, and the temperature of the pasta decreases to below 60 ° C immediately after the addition of water. A similar solution using the AW value is described in EP-A-0 322 053 B1.
Automatizované lisy na výrobu surových cestovín sú napríklad známe z dokumentu EP-A-0 426 766 B1 vo forme miesiaceho a hnetacieho zariadenia, ktoré obsahuje dva pracovné hriadele, ktoré majú striedavo miesiace závitovky a prvky na krájanie, alebo z dokumentu DE-44 17 357 A1.Automated presses for the production of raw pasta are known, for example, from EP-A-0 426 766 B1 in the form of a kneading and kneading device comprising two working shafts having alternating kneading screws and slicing elements, or DE-44 17 357 A1.

-2Technický priebeh a čiastočne parametre spôsobu sú k dispozícii ako riadiace dáta. Riadenie sústav umožňuje riadenie priebehu podľa zvoleného procesu a takisto vizualizáciu stavu sústavy. Čo sa týka snímačov, známe sú napríklad snímače teploty a vlhkosti, snímače otáčok alebo tlakové snímače. Kvôli rozdielnym hodnotám surovín, opotrebovaniu strojov alebo nepresnostiam snímačov sa nemôže uskutočňovať žiadna on-line optimalizácia. Známy je okruh problémov v surovinách, napríklad kolísanie kvality a vlhkosti múky a krupice, alebo vplyvy týkajúce sa ovzdušia v miestnosti, ktoré pôsobí na kolísanie vlhkosti surových cestovín a na podmienky sušenia, ďalej problémy spojené s kvalifikáciou obsluhujúceho personálu, nekonštantnými vlastnosťami strojov a inými vplyvmi.-2Technical sequence and partial process parameters are available as control data. System control allows the process to be controlled according to the selected process as well as system status visualization. As for the sensors, for example, temperature and humidity sensors, speed sensors or pressure sensors are known. No online optimization can be performed due to different raw material values, machine wear or sensor inaccuracies. Known are a range of raw material problems, such as flour and semolina quality and humidity fluctuations, or room air influences that affect raw moisture fluctuations and drying conditions, operator qualifications, non-constant machine properties, and other influences .
Problematickým je aj on-line meranie v teplej a vlhkej klíme sušiča a na rôznych produktoch.On-line measurement in warm and humid climate of the dryer and on various products is also problematic.
Dokument DE-44 33 593 A1 opisuje spôsob regulácie extrudéra, pričom menovité hodnoty regulačného člena sa zadávajú podľa skúšobných dát alebo znalostí odborníkov a ktorého akčné veličiny závisia na kvalite produktu. Podľa zadania menovitých hodnôt sa optimalizuje a stabilizuje pracovný bod a na riadenie strojov sa použije integrovaný regulátor. Takýmto regulátorom riadiacim proces môže byť Fuzzy regulátor. Po vložení a uložení zistených dát do pamäte sa automaticky adaptujú regulácie pre špecifické regulačné dráhy a generujú špecifické regulátory pomocou generátora kódov, ktoré sú integrované do prostredia regulácie.DE-44 33 593 A1 discloses a method for controlling the extruder, wherein the nominal values of the regulating element are set according to test data or the knowledge of experts and whose action values depend on the quality of the product. The operating point is optimized and stabilized according to the nominal values and an integrated controller is used for machine control. Such a process controller may be a Fuzzy controller. When data is stored and stored in memory, the controllers for the specific control paths automatically adapt and generate the specific controllers using a code generator that is integrated into the control environment.
Na uskutočňovanie spôsobu je medzi dýzou a špičkou závitovky extrudéra nainštalovaný in-line snímač viskozity.To carry out the method, an in-line viscosity sensor is installed between the nozzle and the tip of the extruder screw.

-3tovaru, ktoré je ovplyvňované prúdom plynného pracovného média. Podľa vedomostí odborníka sa individuálne zadáva stratégia, ktorá sa uskutočňuje pomocou známeho regulátora Fuzzy. Pritom sa získavajú určité parametre procesu, ako je napríklad teplota tovaru na vstupe sušiča a na výstupe zo sušiča, ako aj vlhkosť tovaru na vstupe a na výstupe sušiča, ktoré sú vstupným dátami Fuzzy regulátora.-3 goods that are affected by the flow of gaseous working medium. According to the knowledge of the expert, the strategy is individually set, which is carried out by means of a known Fuzzy regulator. Certain process parameters such as, for example, the temperature of the goods at the inlet and outlet of the dryer and the humidity of the goods at the inlet and outlet of the dryer, which are the input data of the Fuzzy controller, are obtained.
Podobný spôsob je uverejnený v dokumente DE-44 35 808 A1. Tu sa pri procese na sušenie lisovacích odrezkov určuje obsah vlhkosti odrezkov meraním ich hmotnosti. Obsah vlhkosti, zistený z merania hmotnosti, sa spolu s ďalšími parametrami, ako sú hodnoty teploty alebo množstvo lisovacích odrezkov, zadávajú na vstupy jednotky Fuzzy. Výstupný signál jednotky Fuzzy sa používa ako regulačný signál na sušenie odrezkov pri zohľadnení meniaceho sa obsahu vlhkosti.A similar method is disclosed in DE-44 35 808 A1. Here, the moisture content of the cuttings is determined by measuring the weight of the cuttings in the drying process. The moisture content, as measured by the weight measurement, is entered along with other parameters, such as temperature values or the amount of press cuttings, at the inputs of the Fuzzy unit. The output signal of the Fuzzy unit is used as a control signal for drying off cuttings taking into account the changing moisture content.

Cieľom vynálezu je vyvinúť spôsob optimalizácie riadenia procesu jednotlivých čiastkových procesov v sústave na výrobu cestovín, najmä krátkych a dlhých cestovín alebo podobných výrobkov, ktorý umožní optimálnejšiu reguláciu lisov a sušičov, ako aj monitorovanie procesu použitím inteligentných softvérových technológií. Dosiahnuť sa má najmä jednoduché nastavovanie regulácie a zníženie vadnej produkcie.It is an object of the invention to provide a method for optimizing the process control of individual sub-processes in a pasta production system, in particular short and long pasta or the like, which allows for more optimal control of presses and dryers as well as process monitoring using intelligent software technologies. In particular, simple adjustment of the regulation and reduction of defective production should be achieved.
Podstata vynálezuSUMMARY OF THE INVENTION
Riešenie tejto úlohy sa realizuje podľa znakov nároku 1, pomocou nasadenia inteligentných softvérových technológií, napríklad použitím virtuálneho snímača (tiež „soft senzor“) vlhkosti koncového produktu, s reguláciou množstva dávkovanej vody v lise. Vlhkosť koncového produktu je zmenený listThe solution to this task is accomplished according to the features of claim 1, by employing intelligent software technologies, for example by using a virtual sensor (also a " soft sensor ") of the end product moisture, with control of the amount of dosed water in the press. The moisture content of the end product is a changed sheet
-4možné udržať v prípustných medziach. Doteraz nebolo možné získavať informácie o stave produktu v sušiči. Pomocou on-line snímačov v sušiči sa na meranie vlhkosti produktu a/alebo na meranie hmotnostných strát môže navyše regulovať klimatická krivka a krivka vlhkosti produktu.-4could be kept within acceptable limits. Until now, it was not possible to obtain information on the condition of the product in the dryer. In addition, the on-line sensors in the dryer can be used to regulate the product's moisture and / or mass loss measurements.
Vynález vychádza z poznania, že jednotlivé čiastkové procesy sú na sebe závislé a bodová optimalizácia nezaručuje úspech. Dôvodom je striedavé pôsobenie medzi vlastnosťami produktu a správaním sa strojov. Pomocou štatistických a inteligentných softvérových technológií sa pritom určujú modely parametrov procesu, ako je napríklad nastavenie strojov, suroviny, recepty na zmesi a vlastnosťami produktu, ako je napríklad obsah vlhkosti, farba, viskozita.The invention is based on the recognition that the individual sub-processes are interdependent and point optimization does not guarantee success. The reason for this is the intermittent interaction between product properties and machine behavior. Statistical and intelligent software technologies are used to determine process parameter models such as machine settings, raw materials, mix recipes, and product characteristics such as moisture content, color, viscosity.
Inteligentné softvérové technológie (tiež „Soft Computing“) zahrňujú technológie, ako sú expertné systémy, neurónové siete, Fuzzy Logik a genetické algoritmy (evolučné algoritmy). O týchto je napríklad písané v článku „Soft Computing in der Automation“ od P.Auera, Elektroník 34/1998.Intelligent software technologies (also called “Soft Computing”) include technologies such as expert systems, neural networks, Fuzzy Logic and genetic algorithms (evolutionary algorithms). These are, for example, written in the article "Soft Computing in der Automation" by P. Auer, Electronic 34/1998.
Kombináciou týchto technológií, napríklad neurónovej technológie a technológie Fuzzy, vznikajú hybridné modely, ktoré môžu zohľadniť jednak jestvujúce znalosti expertov (napríklad s Fuzzy regulátormi), tak aj experimentálne dáta (ktoré sa napríklad vytvárajú pomocou štatistického plánovania skúšok a skúšok procesov, a modelujú v neurónových sieťach). Okrem toho sa tieto modely kombinujú s konvenčnými, analytickými modelmi (napríklad založených na fyzikálnych metódach alebo regresných výpočtoch) a označujú sa ako hybridné.The combination of these technologies, such as neural technology and Fuzzy technology, creates hybrid models that can take into account both the existing expertise of experts (for example with Fuzzy controllers) and experimental data (such as generated by statistical test and process planning) and modeled in neural networks). In addition, these models are combined with conventional, analytical models (for example, based on physical methods or regression calculations) and are referred to as hybrid.
Do úvahy prichádzajú aj nové metódy, ktoré umožňujú automatické generovanie modelov (napríklad automatické generovanie štruktúry a parametrov neurónových sietí pomocou genetických algoritmov alebo automatické generovanie regulátorov Fuzzy z dát procesu). Adaptačné prispôsobenie on-line modelov je potom jednoduchšie.New methods are also available that allow automatic generation of models (for example, automatic generation of neural network structure and parameters using genetic algorithms or automatic generation of Fuzzy controllers from process data). The adaptation of online models is then made easier.
Pomocou tohto modelu je možná optimalizácia čo sa týka vlastností produktu, parametrov procesu ako aj nákladov (náklady na suroviny, zmenený list.Using this model, it is possible to optimize in terms of product properties, process parameters as well as costs (raw material cost, changed sheet).
-5prevádzkové náklady). Tým je umožnená cielená, od modelu závislá adaptačná regulácia. Potom sa môžu lepšie regulovať aj nelineárne systémy.-5 operating costs). This allows targeted, model-dependent adaptation control. Non-linear systems can then be better regulated.
Ďalšou úlohou je vytvorenie zariadenia na uskutočnenie spôsobu.Another object is to provide a device for carrying out the method.
Výsledkom je adaptačná regulácia výroby cestovín čo sa týka lisov surových cestovín a ich sušenia/ochladzovania, pričom zariadenie môže byť v prevádzke bez obsluhy. Adaptačné regulácie jednoduchých procesov sú síce známe, ale nedajú sa uplatniť pri takýchto komplexných procesoch.The result is an adaptive control of the pasta production with respect to the raw pasta presses and their drying / cooling, whereby the apparatus can be operated unattended. Adapting regulations for simple processes are known, but cannot be applied to such complex processes.
Použiť sa môžu jestvujúce snímače. Elektropneumatické regulátory na reguláciu klímy v sušičoch sa môžu nahradiť elektromechanickými učiacimi sa regulátormi.Existing sensors may be used. Electro-pneumatic climate controllers in dryers can be replaced by electromechanical learning regulators.
Doplnkovo sa má dosiahnuť citlivý prechod od sušiča / chladiaceho boxu do klímy miestnosti a jej zohľadnením, aby sa minimalizovalo napätie v produkte a tým aj lámanie cestovín.In addition, a sensitive transition from the dryer / cooling box to the room climate and taking it into account should be achieved to minimize product tension and thus the breaking of the pasta.
Pomocou on-line regulácie sa automaticky, pomocou reprodukovateľného, priameho alebo virtuálneho on-line merania vlhkosti produktu kompenzujú poruchy procesu. Meraním klímy v miestnosti a prispôsobením klímy v sušiči v jednotlivých zónach môže byť koncový produkt stabilizovaný. Dosiahnutie je hlavne zníženie počtu lomov koncového produktu cestou do sila.On-line control automatically compensates for process failures by reproducible, direct or virtual on-line product humidity measurement. By measuring the room climate and adapting the climate in the dryer in each zone, the end product can be stabilized. Achieving is mainly a reduction in the number of fractures of the end product by way of silo.
On-line regulácia umožňuje dlhodobé konštantné udržiavanie kritérií pre koncovú kvalitu produktov počas produkcie a tiež pri vznikajúcich poruchách procesu. Prebieha hlavne regulácia na produkt vztiahnutých regulovaných veličín, napríklad vlhkosti produktu. Každá regulovaná veličina by mala byť merateľná a poruchové veličiny je potrebné redukovať. Pri stabilizovaní koncového produktu sa má klíma v miestnosti sledovať v on-line riadení klímy jednotlivých zón sušiča, prípadne aj do vetrania produktu. Lis na cestoviny sa môže použiť aj ako virtuálny snímač vlastností produktu, ako je vlhkosť cesta a jeho konzistencia.On-line regulation allows for constant constant maintenance of the criteria for the final quality of products during production and also during emerging process failures. In particular, there is regulation to the product of the relative controlled quantities, for example the moisture of the product. Each controlled variable should be measurable and the fault variable must be reduced. To stabilize the end product, the room climate should be monitored in the on-line climate control of the individual zones of the dryer, possibly also into the ventilation of the product. The pasta press can also be used as a virtual sensor of product properties such as dough moisture and its consistency.
Asistent receptov automaticky poskytuje prvý údaj o hodnotách receptu, potrebných na špecifické, požadované vlastnosti produktu. Zo zadaných údajov zmenený listThe Recipe Assistant automatically provides the first indication of the recipe values needed for specific, desired product properties. Changed sheet from the entered data
-6o produkte sa pritom generujú štartovacie hodnoty receptu. Na základe náučných dát, znalostí expertov a daných fyzikálnych skutočnostiach prebieha modelovanie a výpočet hodnôt receptu zo zadaných dát. Pri zmene produktu nastáva porovnanie či sú hodnoty receptu pre novozadané údaje o produkte dostatočne podobné.In the process, the starting values of the recipe are generated. Based on educational data, expert knowledge and given physical facts, the recipe values are modeled and calculated from the entered data. When changing a product, it is compared whether the recipe values for the newly entered product data are sufficiently similar.
Nasledujúca optimalizácia receptu sa podporuje pri jemnom nastavovaní vstupných údajov receptu a pomocou diagnózy sa môžu rozoznať a rozlíšiť hrubé chyby, pričom má operátor získať odkazy, ktoré chyby by mal kontrolovať a odstrániť.The following recipe optimization is supported by fine-tuning the recipe input data, and gross errors can be recognized and distinguished by diagnosis, and the operator should get links to which errors should be checked and corrected.
Pri optimalizácii receptu sa pri zavádzaní receptu optimalizujú počiatočné hodnoty a modelujú súvislosti medzi odchýlkou cieľových veličín a zmenou nastavených veličín. Operátor môže nastavovať cieľové kritériá na požadovanú hodnotu a automaticky môžu byť nastavované nové nastavené veličiny. Tak isto je možné aj ručné prispôsobenie.In recipe optimization, the initial values are optimized and the relationship between the deviation of the target variables and the change of the set variables is optimized when the recipe is introduced. The operator can set target criteria to the desired value and new set values can be set automatically. Manual adjustment is also possible.

Vynález je ďalej bližšie opísaný a objasnený na príklade jeho uskutočnenia podľa pripojeného výkresu, ktorý znázorňuje na obr. 1 schematický priebeh v lisovacom zariadení na cestoviny, a na obr. 2 schematický priebeh v sušiči / chladiacom boxe.The invention is described and explained in more detail below with reference to the accompanying drawing, in which: FIG. 1 is a schematic diagram of a pasta press, and FIG. 2 shows a schematic diagram in a dryer / cooling box.
Príklady uskutočnenia vynálezuDETAILED DESCRIPTION OF THE INVENTION
Z dávkovacej jednotky 1, v ktorej sa dávkujú a zmiešavajú krupica a/alebo múka, ako aj voda a prísady, sa suroviny dostanú do miesiaceho a hnetacieho zariadenia 2, napríklad podlá dokumentu EP-A-0 426 766 B1, kde prebieha intenzívne miešanie a hnetenie surovín na surové cesto.From the dosing unit 1, in which the semolina and / or flour, as well as the water and the ingredients are dosed and mixed, the raw materials are conveyed to the mixing and kneading apparatus 2, for example according to EP-A-0 426 766 B1. kneading raw materials on raw dough.

-7Surové cesto sa na konci miesiaceho a hnetacieho procesu dostáva do lisovacej závitovky 3 miesiaceho a hnetacieho zariadenia 2, ktorým sa vyrábajú surové cestoviny. Pri dlhých cestovinách nasleduje difúzor 4.At the end of the kneading and kneading process, the raw dough reaches the pressing screw 3 of the kneading and kneading device 2, which produces raw pasta. For long pasta, diffuser 4 follows.
Potom sa mokré surové cestoviny s obsahom vlhkosti cca 30 % privedú do natriasacieho sušiča 5 a potom do predsušiaceho zariadenia 6 a koncového sušiča 7 a chladiaceho boxu 8, v ktorých sa uskutočňuje sušiaci proces podlá dokumentov EP-A-129892 a/alebo EP-A-540699. Cestoviny opúštájú chladiaci box s obvyklou vlhkosťou produktu 11 až 13 %, výhodne 12,5 %. Následne sa usušené cestoviny zvyčajným spôsobom režú a balia.Thereafter, the wet raw pasta with a moisture content of about 30% is fed to a shaking dryer 5 and then to a pre-drying device 6 and an end dryer 7 and a cooling box 8 in which the drying process is carried out according to EP-A-129892 and / or EP-A. -540699. The pasta leaves the cooling box with a typical product moisture of 11-13%, preferably 12.5%. The dried pasta is then cut and packed in the usual manner.
V jednotlivých častiach sušiča 5, 6, 7 a v chladiacom boxe 8 sa pomocou on-line snímačov 9 neustále sleduje vlhkosť produktu a straty hmotnosti cestovín. Takýto on-line snímač 9 možno umiestniť aj v lisovacej závitovke 3, prípadne v difúzore 4.In the individual parts of the dryer 5, 6, 7 and in the cooling box 8, the on-line sensors 9 constantly monitor the moisture of the product and the loss of weight of the pasta. Such an on-line sensor 9 can also be placed in the press screw 3 or in the diffuser 4.
Pomocou výslednej regulácie klímy je tiež možné udržať vlhkosť produktu veľmi blízko optimálnej vlhkosti 12,5 % a v konečnom dôsledku podstatne znížiť chybnú produkciu pri konštantnej kvalite cestovín.Thanks to the resulting climate control, it is also possible to keep the product moisture very close to the optimum humidity of 12.5% and, ultimately, to significantly reduce misproduction at a constant quality of pasta.
